SAFETY-RAZOR.

-. the following is a full, clear, and exact descri tion.

T e lnventlon relates to safety razors,

such as are shown and described in the'Letters Patent of the United States, No. 931,778,

granted to me on August 24, 1909.

The object of the present invention is to provide a new and improved safety razor,

arranged to accommodate different makes of thin, flexible blades, and permit ready stropping of the blades and adjustment of the latter relative to the guard, for close shaving.

For thepurpose of accommodating difierent razor blades,--use is made of a pair of clamping plates, and'adjustable means for en aging the apertures, slots or notches in diderent makesof razor blades, at the time they are clamped between the plates. In ormgs forming apartof section of the safety der to allow ready stropping of the razor blades, use is m ade'of a tubular back hinged to one of the clamping plates and adapted to straddle the same, so as to rise even distances from the outer faces of the plates, and in order to rovide for the adjustment of the razor bladbs for close shaving use is made of a liner interposed between the guard plate and the razor blade.

A practical embodiment of the invention is represented in the accompanying drawwhich similar characters of reference indicate corresponding parts in allthe views.

Figure 1 is a plan view of the safety razor showlng the razor blade in position for shaving; Fig. 2 is aside elevation of the safety razor showing the razor blade in position for stropping;

Fig. 45is an enlarged cross razor, the section beingon the line 44: of Fig. 1; Fig. '5 is a similar view of guard plate with a Gillette razor blade in position thereon, together with a liner to clamping the locking the studs D, D

this specification, in

line 7-7 of Fig. 6; Fig. 8 is a perspective view of the liner; and of part of the guard plate with a razor blade thereon having notches at the ends.

The guard plate A and the locking plate B of the safety razor are connected together so that one overlies the other, to permit of clamping the razor guard end A of the guard plateA and the end B of the clamping plate B. The guard plate A is provided in one side edge adjacent to the guard with a notch and plate B is formed with an offset and provi ed with a notch in said ofl'set so that when the parts are interlocked as shown in the drawings, the ends of the locking plate lie on opposite sides of the guard plate. In, the guard end A of the plate A are formed elongated slots A A ranging lengthwise of the plate A, and-in which are mounted to slide studs D, D projecting into slots B B formed in the clamprn end B of the clamping plate B. The stu s D and D are adapted to enga e difierent makes of razor blades, so as to ho d the same against lateral movement, while in position between the ends A and B of the plates 'A and B; for instance, as shown in Fig. l, the razor blade C is provided with an elongated slot C, through which pass at the time the razor blade is interposed between the ends A and B of the guard plate A and the clamping plate B. In Fig. 6, is shown a Gillette razor blade C having the usual apertures, of

ard.

blade C between the which the end ones. are-enga ed y the studs D and D and in the razor lade illustrated in Fig. 9, the ends thereof are rovided with notches C which are engaged by the studs D and D. Thus by the arrangement de- D and D engage the razor blades of different makes, by shifting'the said studs D and D in the longitudinal slots A A, B B to hold the razor blades against lateral movement during they are held between the ends and B of the guard plate A and the clamplng plate B.

When it is desired to strop a razor blade, then it is clamped between the stropping ends A, B of theguard plate A and the 105 clampin plate B, the saidend A being provider? with elongated slots A, A, in which are mounted to slide studs and E, adapted to engage the correspond ng. slots,

apertures or notches of the various makes no the time noticed that the studs 1) and of razor blades in the same way as above described relative to the studs D and D. The studs E and E are adapted to project into corresponding slots 13", B formed in the end B of the clamping plate B.

a, blade C is in stropping position one cuttin edge of the blade projects a distance beyon the corresponding edges of the ends A, B

In order to lock the plates A and B together use is made ofla split tube F, provided at one end with an ear F fulcrumed at F on the end A" of the ard plate A.

By the arrangement describe thesplit tube F may be swung inward, to straddle the ends A", B, so as to lock the plates together at the time-a razor blade C is clamped either between the ends A, B for shaving pur; poses (seeFigs. 1 and 2) or between the ends,A B for stropping purposes, as indicated in Figs. 3 and 5.

By reference to Fig. 5, it will be noticed that the tube F rises the same distance frdm the outer faces of the ends A, B, and consequently when the'plate C is stro ped, the angle at the cutting edge of the b ade C is the same during the forward and backward stropping movement of the device on the razor strop.

When it is desired to unlock the plates A and B, it is only necessary for the operator to swing the tube F out of straddling contact with the ends A B, as indicated in; Fig. 3, to allow of taking the guard plate A. an the clamping plate B apart by swinging one relative to the other into angular positions, as indicated in dotted lines in Fig. 2.

"tion on the end A 'for removing it therefrom.

It is understoodthat for shaving purposes I T For close shavin a liner G is interposed between the razor blade and the ard end A of the guard plate A, as in icated in Flgs. 6 and 7, so as to raise the cutting edges of the razor blades farther from the guard prongs, to allow holding the safety razor in a closer shaving position than would be the case if the liner were removed and the cutting edges of the blades were closer to the guard prongs.

The liner 1s referably-made U shape, to straddle the stu s D, D, thus holding the razor against sidewise movement, the liner being provided at the closed end with a flange G ada ted to be taken holdof by the operator, or placing the liner in posiof the guard plate A or the ends A, B' are used as a handle for manipulating the safety razor, and when the device is employed for stropping a razor blade, the 'ends'A, B form a handle, taken hold of by theloperator for drawing the blade over the strop with the tube also in I contact with the strop.

Having thus described my invention, I claim as new'and desire to secure by Letters Patent:

1. In a safety'razor, a pair of plates between which a razor blade is to be held, one of the plates being provided with a guard,

the plates being each provided with two slots, and studs slidably held in the slots of one late and in sliding engagement with the s ots of the other plate.

2. In a safety razor, a pair of plates hav ing interlocking engagement whereby the plates willlie on opposite sides at opposite ends, 'the said plates being each provided at each end with a pair of slots, the slots at one end bein centrally, arranged andflthe slots at the ot ler end being near one edge, studs slidably held in the slots of one plate and in sliding engagement with the slots of the I other plate, and means for securing the plates togethen:

3. A safety razor, plates having interlocking engagement, whereby the plates will lie on'opposite sides at opposite ends, one of the plates at one end being formed with a guard, and both plates sides 0 the center, being centrally arranged and the slots atthe opposite end being'near one edge, studs slida-bly mounted. in the said slots, and a split tube pivoted to one or the plates and "straddling the said plates to form a back for the same. M a

4. In a safety razor, the combination of a guard plate, a razor blade, and a detachable liner in the form of a plate interposed between the guard plate and razor blade to space the blade from the guard.

5. In a safety razor, the combination of a razor blade, a guard plate, a clamping plate,

between which and the said guard plate the said blade is clamped, studs held on one of the said lates and engaging the said razor blade, an a detachable Ushaped liner plate interposed between the said guard plate and the said razor blade to'space the blade from the guard, the liner plate straddling the said.

studs. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
